I have one on the top of my left hand; it's tiny and looks like a weird spoon. Or maybe a brush or something, Idk. Anyway, there's a fun story behind it: In January 2010, my entire tenth grade (I was in a tiny private school; there were fewer than ten people in my grade) went to study in a sister school in upstate NY for a month. One of the things we studied was some form of chemistry—I can't remember the specific category. At some point, our teacher put a tiny bit of hydrochloric acid on our hands. After a few seconds (he wanted to wait until it started burning), we were to immediately wash it off. I was a bit too late, and voila! I got a scar.

There's also one around my hip area. I got it from my friend pulling me off the stairs of a wooden playground set back in eighth grade. I was still sitting as he did so and slid off. The set pretty much scraped my sides. It hurt like hell x_x
